Ive been noticing a soft spot on my 1994 sea ray bow rider around the edge of the ski locker, well after a day of checking and digging I have found that the plywood is completly rotted out for about three inches around the back side of the locker. all of the rest of the deck seems to be in good shape. Is there any way to fix this without having to completly replace the decking? I think this is the last year for me and this boat so my other question is if I do have to replace the all the decking is it worth it for the resale?
